The Veggie version of our Down-O-Matic helmet uses a technology unlike any other helmet currently on the market. The shell is constructed of a fiber that has characteristics much like a carbon fiber but is made from a plant. The use of this material is much cleaner in production as well as better for the environment years after you are done with your helmet. This also makes a helmet that is lighter than our all fiberglass version while meeting all of the same certifications. Plus the raw Veggie sections of the helmet look really cool too. Available in S/M (54 - 57CM and L/XL (57 - 60CM).
